Passage
My son, forget not my law; but let thine heart keep my commandments:
My son, forget not my law; but let thine heart keep my commandments:
Proverbs 3:1 My son, forget not my law; but let thine heart keep my commandments:
Proverbs 3:2 For length of days, and long life, and peace, shall they add to thee.
Proverbs 3:3 Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart:
The verse centers on "forget", "thine", "heart", "keep", and "commandments". It is saying that the verse draws attention to "forget" and "thine", so its meaning should be read from those terms before moving to application.
The next verse adds "For length of days and long life...", so "forget" and "thine" should be read forward into that movement. In Proverbs context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "forget" and "thine" with trust shaped by these words, not by a vague optimism outside the passage.
